Colt 1860..finally got one.

[Doco overboard]

This is the one, passed down to me. I do not know if it's a martial or civilian model for lack of literature. It has a recessed area in the grip frame but no engraving on the cylinder unless it's been worn away.
Looks like a lot of muzzle wear from being carried or transported on the right side which for some reason makes me think occurred from a peculiar way of travel or storage which is just all speculation on my part.
